I have some general questions concerning what to do with some of these stamps. I do understand that you are passionate collectors and I do not have enough time in my life to gather the knowledge that you all have. I have attached two scans just for grins. In general, in order to sell some stamps as carmine or lake variations, do they need to be expertise? Also in the case of the C23, I know this stamp is of minimal value, but I do possess 23 of the middle of the page examples never hinged. Do I just offer them as fine or VF or what would you recommend.
Thanks again. JoJo
